Meet Mercy Blain, whose house has just burnt down.

Unfortunately for Mercy, this goes beyond the disaster it would be for most people - she hasn’t been outside that house for two years now. Flung out into the world she’s been studiously ignoring, Mercy goes to the only place she can. Her not-quite-ex-husband Eugene’s house. But it turns out she can’t stay there, either.

And so begins Mercy’s unwilling journey. After the chance purchase of a cult classic campervan (read tiny, old and smelly), with the company of her sausage dog, Wasabi, and a mysterious box of cremated remains, Mercy heads north from Adelaide to Darwin.

On the road, through badly timed breakdowns, gregarious troupes of grey nomads and run-ins with a rogue adversary, Mercy’s carefully constructed walls start crumbling. But what was Mercy hiding from in her house? And why is Eugene desperate to have her back in the city? They say you can’t run forever …
